Central pterygium of right eye
ICD-10 H11.021 is a billable code used to indicate a diagnosis of central pterygium of right eye.
Central pterygium of the right eye is a benign growth characterized by a triangular-shaped fibrovascular tissue that extends from the conjunctiva onto the cornea. This condition typically arises due to chronic irritation, often from environmental factors such as UV exposure, wind, and dust. Clinically, patients may present with symptoms like redness, irritation, and visual disturbances if the pterygium encroaches on the visual axis. The anatomy involved includes the conjunctiva, cornea, and potentially the sclera, as the pterygium can affect the underlying structures. Disease progression may lead to increased growth, which can cause astigmatism or other refractive errors. Diagnostic considerations include a thorough ocular examination, where the pterygium's size, location, and impact on vision are assessed. Slit-lamp examination is crucial for evaluating the extent of the growth and any associated corneal changes. Management may involve observation for asymptomatic cases, while surgical intervention may be necessary for symptomatic patients or those with significant visual impairment.

H11.021 specifically covers central pterygium of the right eye. It is important to differentiate it from other types of pterygium, such as nasal or temporal, and from other conjunctival lesions.
H11.021 should be used when the pterygium is specifically located in the central area of the right eye. If the pterygium is located in a different area or affects the left eye, the appropriate code should be selected.
Documentation should include a detailed ocular examination report, noting the size and location of the pterygium, any symptoms experienced by the patient, and the rationale for treatment decisions, especially if surgical intervention is planned.
